My headlights (110 W lows, 400 W highs) are completely relayed, and my
switch still gets hot. I don't know if that makes yours "good" or "bad,"
but it's another data point; '87 4kq.

Re-wrapping is an OK idea, but they probably need to be re-placed. BTDT

Dunno about the "euro" number, but a two-filament 1157 draws ~2.5 amps
through _both_ filaments. Your 3.X A sounds about right to me for three
bulbs.
